I have a glass & metal umbrella table that needed to have the metal frame glued to the underside of the glass. I flipped the glass table upside down on another table. I clamped the corners down and applied the GE silicone. I went to Home Depot and bought two more tubes. It is now twenty-four hours later, and it is still wet to touch. Where do I go from here? If it never sets up, then I cannot apply the next layer. With uncured silicone residue and re-apply because it will not adhere. What to do now?
If it smells weird and never sets up, it's too old. The only way to fix things is to clean it up with acetone or mineral spirits and start fresh with a tube that is within expiration. If you bought the tubes recently and they were already expired, bring them back and exchange them at the home store.
